Everyone considering a professional career in security research, RE, and Malware Analysis needs to know YARA Rules. YARA Rules are used throughout the industry next to STIX 2.1 Standard to classify and identify malware. It's in essence, pattern matching utilizing static signatures from strings, IOC's and other unique identifiers close to functionality as possible. You can't use the digest/hash on a family that mutates with new variants and forks every week so YARA fixes that problem. I encourage you to get familiar and read the docs which I will link below. I write YARA rules for every analysis I conduct and I post on openbin.ai yara.readthedocs.io/en/stabl… #cybersecurity #malware #reverseengineering #malwareanalysis

Cymru recently posted addresses related to interesting infra with history - our TLPBLACK sensors tracked attacks from some of these IP going back to august 2025
Replying to @teamcymru_S2
Self-hosted AI-quota gateways are showing up as live attack infrastructure. We're currently tracking 241 IPs running New API and Sub2API panels (gen-ai:new-api / gen-ai:sub2api) that double as C2, recon, and proxy nodes across 46 ASNs in Hong Kong, the US, Singapore, and China. C2 controllers: 103.194.106.229 cyberstrikeai + new-api 185.242.235.16 cyberstrikeai + overlord-rat + new-api 66.154.108.173 adaptixc2 + proxy:nps + new-api 101.37.210.236 supershell + sub2api 35.78.107.61 adaptixc2 + sub2api Recon + offensive-sec tooling: 124.222.164.176 ost:arl + new-api + openclaw 152.32.252.32 ost:arl + new-api 38.76.169.125 ost:gophish + new-api FRP tunnels + brute-force: 183.250.89.44 proxy:frp + scanner:brute-force + new-api 38.148.249.2 proxy:frp + scanner:brute-force + new-api 45.145.228.130 proxy:frp + new-api

Two U.S. Nationals Sentenced for Facilitating Fraudulent Remote Information Technology Worker Scheme that Generated $5M in Revenue for the Democratic People’s Republic of Korea “For years, the defendants enriched themselves by assisting North Korean actors in a fraudulent scheme to gain employment with U.S. companies,” said Assistant Attorney General for National Security John A. Eisenberg. “The ruse placed North Korean IT workers on the payrolls of unwitting U.S. companies and in U.S. computer systems, thereby harming our national security. NSD will hold accountable those who facilitate North Korea’s illicit revenue generation efforts.” 🔗: justice.gov/opa/pr/two-us-na…

The @FBI has identified cyber actors associated with Russian Intelligence Services targeting users of commercial messaging applications, including Signal. The campaign targets individuals of high intelligence value, including current and former U.S. government officials, military personnel, political figures, and journalists.   Globally, this effort has resulted in unauthorized access to thousands of individual accounts. After gaining access, the actors can view messages and contact lists, send messages as the victim, and conduct additional phishing from a trusted identity. It's important for you to be aware and take action - this vulnerability is not with the application - but you as the end user.   The FBI and CISA have released a joint PSA to help you identify this activity and protect your accounts: ic3.gov/PSA/2026/PSA260320

Today the Danish Defence Intelligence Service attributed two cyberattacks to Russia. We strongly condemn these attacks against a Danish water utility and Danish websites during elections in DK. We call on Russia to cease these malicious cyber activities fe-ddis.dk/globalassets/fe/d…

It’s been a while since I read a good blog post about WiFi hacking tricks. The hack does not necessarily have to be complex to work.
